TOBACCO-PIPE.

Specification of Letters Patent.

Patented Apr. 6, 1926.

Application filed October 18, 1918. Serial No. 258,697.

To all whom it may concern Be it known that I, LOUIS SUEDMEYER, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Tobacco-Pipes, of which the following is a specification.

This invention relates to pipes, and has for its object to provide a pipe in which the products of condensation from the tobacco will be removed during smoking and can be readily discharged at any time by the smoker; which will thoroughly filter and cleanse the smoke after the removal of the products of condensation; which will protect thepipe material and stem from becoming saturated with the liquid distilled out of the tobacco during smoking; and which may be readily adapted to a new bowl and stem without the necessity of procuring a new bit and cleaner.

In the drawings herewith I have illustrated one embodiment of my invention, but it will be understood that this illustration as well as the descriptive portion of this specification are in no sense restrictive of the invention, as it may be varied within the range of mechanical skill without departing therefrom.

In said drawings Figure 1 is a longitudinal. sectional view vertically of a pipe made in accordance with my invention.

Fig. 2 is a view in plan, partly in section.

Fig. 3 is a transverse section on substantially the line 3-3 of Fig. 1 to illustrate the construction of one of the cleaner pockets.

Fig. 4 is a longitudinal sectional view vertically showinga slightly different adaptation of the invention.

Fig. 5 is a longitudinal section of the cleaning device proper, showing a further adaptation of the invention.

Fig. 6 is a transverse section on substantially the line 6-6 of Fig. 1.

Fig. 7 is an end View of a bit peculiarly adapted to be used with my invention.

Fig. 8 is a transverse section through the structure shown inFig. 5.

Fig. 9 is a view in section illustrating a slightly different disposition of the purifying device in the stem of the pipe. 7

Fig.'10 is a sectional view showing the to a curved stemmed pipe.

Referring to the drawings by numbers,

like numbers indicating like parts in the several views, 10 indicates a pipe bowl of any desired shape or material, the form here shown as the ordinary briar pipe. The stem 11 projects from the bowl in the usual manner, a straight stein being here shown extending at right angles from the pipe, although it will be understood that the stem. may extend at other angles to the pipe and be still adapted to the use of my invention. The stem is finished with the usual ferrule 12, if desired.

The stem 11 is provided with the smoke passage 13 from the bowl, this smoke passage extending through a relatively thin partition or wall 1 between the bowl and the main bore of the stem. The bore 15 of the stem is somewhat larger than is customary and extends from the wall 14 to the rear of the stem so as to furnish a relatively large passage lengthwise of the stem.

Within this bore 15 of the stem 11 is the smoke purifying device proper which comprises a member 16, preferably cylindrical in cross section and made of any suitable material impervious to moisture, for example, metal, a light alumina alloy being a good material from which to construct the member 16. The purifying member 16 has in its forward end wall, and preferably above the horizontal center thereof, a draft hole 17 which coincides with the smoke passage 13 in the wall 14:, the end wall of the smoke purifying member 16 fitting snugly against the wall 1% when the member 16 is in the bore of the pipe. The draft hole 17 leads to a well or pocket 18, referably of cylindrical form, in the member 16, this pocket being open at its top and having its side walls slightly inclined and bottom wall curved into the side walls so as to eliminate crevices or interstices so far as possible. The pocket 18 communicates by a tangentially-placed passage 19 with a second pocket 18 of similar form, and said second pocket by a tangential passage 19 disposed on the opposite side of the second pocket and out of line with the first-named passage 19 communicates with a third pocket of similar form as those described. From the third pocket 18 a draft passage 20 leads to a chamber 21 in the rear of the member 16,

the passage 20 being preferably barred or screened by the bars 22.

It is obvious that the number of pockets 18 may be increased or diminished as desired without departing from the spirit of the invention, as the number of pockets used will depend on the style of pipe, the length of stem, and the needs of the particular user.

The action of the purifying member as thus far described will be to lead the smoke through the draft passage 17 into the cylin drical pocket 18 in which the smoke, due to the curved wall of the passage, will be given a whirling motion, which will throw down by centrifugal action the impurities or heavy content of the smoke, and at the same time, by reason of its increased length of travel, cool it before it passes, under draft, through the passage 19 leading to the second pocket. The passages 19 being staggered or out of line with one another, this same g'yrating movement of the smoke, throwing down of the heavy content, and cooling of the smoke will occur in each of the pockets, and the inclination rearwardly of the walls of the pockets will, of course, tend to carry the purified smoke upwardly as it passes from pocket to pocket toward the passages 19', which. are cut in the upper edges of the pocket separating web.

The smoke thus cooled and purified of the heavier products thrown down into the pocket passes by the draft passage 20 to the chamber 21, which chamber is of sufficient capacity to receive a filtering medium,- such as cotton or other suitable material 23, and

this filtering material will be packed inin a loose manner so as not to check or interfere with the draftthrou'gh the pipe, the bars 22 preventing the material from entering the draft passage 20 and clogging. The chamber 21 will be closed at its rear end by any suitable bit 24, the said chamber being tapered so as to give the usual wedging fit between the bit and chamber, and preferably the bit will be provided across its draft passage with a suitable screen or bar 25 to prevent the filtering material 23 from being sucked into the draft passage of the bit.

The member 16 is preferably tapered at its rear end, as at 26, to give the usual wedging fit 'in the bore of the stem 11, although it will be understood that any other connection desired can be adopted other than the tapering wedging connection shown. The tapered portion of the member 16not only gives the proper wedging action to secure the parts together, but it projects rearwardly from the stem of the pipe so that it may be readily grasped to withdraw the purifier without soiling the fingers and without .the necessity of putting. any undue breaking strainon the bit. described the member 16 as having its rear end tapered, it will be understood that the taper may, if desired, extend the entire length; of the purifying device so as to give a good wedging fit in h bore of the pipe.

While I have pockets escaping in the bore of the stem by reason of the member 16 being in inverted position is eliminated.

It will be seen that in the construction described, the smoke will be completely purified, cooled and filtered beforereaching. the mouth of the user, and the fluids and products of condensation in the smoke will be kept from contact with the material of the pipe and stem, and danger of saturation and fouling of the pipe and stem until they become disagreeably strong is eliminated.

It will be seen that none of the collected impurities can run forward into the bowl of the pipe for they are effectively trapped in the pockets and cannot escape therefrom by way of the draft passages either for wardly into the bowl of the pipe or rearwardly into the mouth of the smoker. Furthermore, the construction is such asto a dmit of ready cleaning of the smoke-purify ing member 16 for the user can at any time withdraw the. member 16 and throw tl e contents of the pockets out, and he can also very readily remove the bit and the filter-i ing material can be withdrawn from the chamber 21 and renewed. The cylindrical shape of the pockets 18' lends itself to the ready cleaning of the member, for there are no corners or interstices in which the products of condensation thrown down can accumulate, the walls of the pockets 18 being smooth, and the bottoms being rounded, as shown, so as to present practically no places for lodgment of foreign matter. After continued use, and when it is desirable to completely freshen up the member 16, it may be removed and subjected to any cleaning desired, for example, heating or boiling to very completely cleanse it of any deposits.

In that form of the invention shown in Fig. 5, I have illustrated the smoke-purifying member as being provided with a projection 36 at its forward end' designed to register with the draft passage 13 in the wall 14 between the bowl'and the bore of i tion, for it will be understood that the par- 6 tition 1 1 between the bowl and the bore 15 of the stem 11 is for the purpose of insulating the cooling member 16 from the bowl, so that the said member will not become over heatedifro'm-the howl contents; Where the projection 36 is off-center, as here shown, it will serve also as a registering means to insure the member 16 always being inserted in the bore 15 of the stem in such position as'to maintain the pockets 18 in a vertical position within the stem.

In order to prevent any contact of the smoke or thrown-down products of the smoke with the material of the stem and a resulting saturation of that material, the member 16 may be provided, if desired, with a thin shell 28, as shown inFig. 4, which shell will have a retaining rim 29 at its rear end, so that it may be withdrawn when the member 16 is taken out for cleaning, and slipped off such member to permit the contents of the pockets to be thrown out.

A variation of this shell 28 is illustrated in Figs. 5 and 8, in which a cover plate 30 is provided of sufiicient area to cover the pockets 18, as shown.

It will be observed that in that form of the invention disclosed in Fig. 9 the purifier 31 is difierently disposed with respect to the pipe bowl, the orifice in the front wall of the purifier being dispensed with and the bore 32 in the stem being extended forwardly beneath the bowl pocket 33, so as to bring the first cell or pocket of the purifier directly beneath the draft passage 34 in the bottom of the bowl. This results in the first pocket or cell forming a receiving chamber for any drainage or products of condensation in the bowl so that the bowl will be properly freed of any liquid products which collect in the bottom and they may be readily removed and thrown out of the purifier.

In Fig. 10 the device is shown as applied to a pipe 10 having a curved stem having the" usual ferrule 12 as in the other forms. The purifier 16, which is tapered throughout its length in order to snugly fit the bore of the stem, has the closed end wall similar to the form shown in Fig. 9, and the smoke passage 35 is arranged at an incline, as shown, so as to deliver to the first pocket 18, the pockets being connected as in the other forms by the offset passages 19, the rear wall having the opening 20 forming a smoke passage to the filtering chamber at the rear end of the purifier, which filtering chamber receives also the end of the bit.

It will be observed from the foregoing that a pipe is provided in which the smoke will be thoroughly cleansed and cooled before reaching the mouth of the smoker; in which the products eliminated by the cleansin process may be quickly and without difiiculty thrown from the pipe and this may be done while the pipe is in use and without the necessity of throwing out the tobacco charge and interrupting the smoking to an appreciable extent for purposes of cleansing. Furthermore, the device may be very cheaply constructed, and as has been heretofore stated, may be fitted to a new bowl or stem without the necessity of renewing it or the bit.
